- A regression model relating x, number of salespersons at a branch office, to y, annual sales at the office (in thousands of dollars) provided the following regression output. Where n total = 38. (NEED ANSWERS FOR A, B, C, D)A group of researchers surveyed 58 people when they first started using Facebook [the researchers called this "Time 1"] and again 6 months later [ referred to as "time 2" by the researchers].at both time points, the participants completed a measure of social integration [a sense of belonging to a group of friends]. assuming the measure of social integration was on an ordinal scale, what statistical test would the researcher use in testing their hypothesis?

Although the two lines are exactly the same length, the vertical line appears to be much longer. To examine the strength of this illusion, a researcher prepared an example in which both lines were exactly 10 inches long. The example was shown to individual participants who were told that the horizontal line was 10 inches long and then were asked to estimate the length of the vertical line.

Hint: Help License Points possible: 1 This is attempt 1 of 3. Message instructor about this question SubmitDocument (5) Saved Parents often wonder, usually out of sheer curiosity, how tall their child will be as an adult. When a child has a medical condition or appears to be growing abnormally, the need to under-stand his or her growth can be important. One early method involved simply doubling a child's height at age 2. This gave very inaccurate results, especially for girls. As a result, many better methods have been developed to try to accurately predict a child's eventual adult height from various factors. 1. One simple method to predict adult height is to average the parents' heights and then add 2.5 inches if the child is a boy or subtract 2.5 inches it the child is a girl. This method can be fairly accurate, but can also be as much as 5 inches above or below the child's eventual height. Write a formula or formulas to express this calculation, and clearly define any variables that you use. 2. Another method is to add the parents' heights and then add an additional 5 inches if the…
